- Mateo tiene un puesto de comidas rápidas; en él vende cada hamburguesa a $6.000 y cada perro caliente a $ 3.500. Si la venta total del día fue de $450.000 y se vendieron 110 productos. ¿Cuántos productos de cada uno se vendieron?
x= Hamburguesa
y= Perro caliente
x + y = 110
6000x + 3500y = 450000
x = 110 – y
6000(110 – Y) + 3500y = 450000
660000 – 6000y + 3500y = 450000
660000 – 2500y = 450000
– 2500y = 450000 - 660000
